John Oliver's anti-Donald Trump hat campaign became an unexpected hit

Back in the early days of the election season, in 2015, the host
of "Last Week Tonight" didn't think he had to pay much attention
to Trump as a presidential candidate, he told Stephen Colbert on
Monday night's "Late Show."

But when Trump began to secure a delegate lead in the Republican
primaries, Oliver's show quickly caught up,
dedicating an entire show to decimating the real-estate mogul
and crafting a joke hat to sell to viewers.

Playing off Trump's campaign slogan "Make America Great Again,"
the hat says "Make Donald Drumpf Again"; Trump's family name used
to be Drumpf.

"The German language is so sonorous, isn't it? Beautiful
language," Oliver joked, saying he wanted his audience to see
Trump with "fresh eyes."
